Constructor Detail

POIXMLRelation

protected POIXMLRelation(String type,
                         String rel,
                         String defaultName,
                         POIXMLRelation.NoArgConstructor noArgConstructor,
                         POIXMLRelation.PackagePartConstructor packagePartConstructor,
                         POIXMLRelation.ParentPartConstructor parentPartConstructor)

Instantiates a POIXMLRelation.

Parameters:

type - content type

rel - relationship

defaultName - default item name

noArgConstructor - method used to construct instances of this relationship from scratch

packagePartConstructor - method used to construct instances of this relationship with a package part

POIXMLRelation

protected POIXMLRelation(String type,
                         String rel,
                         String defaultName)

Instantiates a POIXMLRelation.

Parameters:

type - content type

rel - relationship

defaultName - default item name

Method Detail

getContentType

public String getContentType()

Return the content type. Content types define a media type, a subtype, and an optional set of parameters, as defined in RFC 2616.

Returns:

the content type

getRelation

public String getRelation()

Return the relationship, the kind of connection between a source part and a target part in a package. Relationships make the connections between parts directly discoverable without looking at the content in the parts, and without altering the parts themselves.

Returns:

the relationship

getDefaultFileName

public String getDefaultFileName()

Return the default part name. Part names are used to refer to a part in the context of a package, typically as part of a URI.

Returns:

the default part name

getFileName

public String getFileName(int index)

Returns the filename for the nth one of these, e.g. /xl/comments4.xml

Parameters:

index - the suffix for the document type

Returns:

the filename including the suffix

getFileNameIndex

public Integer getFileNameIndex(POIXMLDocumentPart part)

Returns the index of the filename within the package for the given part. e.g. 4 for /xl/comments4.xml

Parameters:

part - the part to read the suffix from

Returns:

the suffix

getNoArgConstructor

public POIXMLRelation.NoArgConstructor getNoArgConstructor()

Returns:

the constructor method used to construct instances of this relationship from scratch

Since:

4.1.2

getPackagePartConstructor

public POIXMLRelation.PackagePartConstructor getPackagePartConstructor()

Returns:

the constructor method used to construct instances of this relationship with a package part

Since:

4.1.2

getParentPartConstructor

public POIXMLRelation.ParentPartConstructor getParentPartConstructor()

Returns:

the constructor method used to construct instances of this relationship with a package part

Since:

4.1.2

getContents

public InputStream getContents(PackagePart corePart)
                        throws IOException,
                               InvalidFormatException

Fetches the InputStream to read the contents, based of the specified core part, for which we are defined as a suitable relationship

Throws:

IOException

InvalidFormatException

Since:

3.16-beta3
